Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
Fig. 1 has provided and has realized system environments schematic diagram of the present invention, two " terminals " among Fig. 1 refer to local video conference terminal and teleconference television terminal respectively, correspondingly, " link " and " network " among the figure refer to video conferencing link and video conference networks respectively, and both form the video conferencing circuit jointly.Local video conference terminal and teleconference television terminal pass through video conferencing link access session TV network respectively, thereby realize data passes and information exchange end to end.The present invention is delivered to an other teleconference television terminal with software code from local video conference terminal by the video conferencing circuit, thereby realizes software upgrading.
Fig. 2 is the flow chart of method for upgrading software according to an embodiment of the invention.In the present embodiment, with video conferencing circuit H.320 is that example illustrates software upgrade process of the present invention, wherein local video conference terminal and teleconference television terminal are respectively this locality H.320 video conference terminal and long-range H.320 video conference terminal, and abbreviate local video conference terminal A and teleconference television terminal B respectively as.As shown in Figure 2, the method flow of present embodiment is as follows:
In step 205, for this locality H.320 video conference terminal be equipped with and be used for teleconference television terminal B is carried out upgrading software.Promptly adopt and local video conference terminal A can be visited when needed be used for the upgrading software code.For this reason, can take multiple different allocating method, for example: software code can be kept on floppy disk, CD or the USB flash disk and offer local video conference terminal A by the corresponding driving device, also can be stored among the RAM or ROM of local video conference terminal A, even can leave on the WEB server that local video conference terminal A can visit by certain mode.In the present embodiment, local video conference terminal A is used for upgrading with its software code that is moving, and the RAM that can directly visit himself does not have the process of independent outfit software code to obtain corresponding software code.
In step 210, between local video conference terminal A and teleconference television terminal B, realize unidirectional and bidirectional data transfers mechanism.In the present embodiment, local video conference terminal A as the one-way data transmission, is used as bidirectional data transfers with video channel with the LSD channel.Fig. 3 is a process flow diagram of realizing unidirectional and bidirectional data transfers mechanism between local video conference terminal A and the teleconference television terminal B in the present embodiment.As shown in Figure 3, this process flow comprises:
In step 305, making needs the two station terminal A and the B that participate in upgrading to enter a H.320 meeting that newly begins, this two station terminal must have by the LSD channel transfer ability of message H.281, if what this two station terminal entered is a multipoint conference, then require MCU (multipoint control unit) also to have corresponding ability;
In step 310, judge whether the meeting of current new beginning is multipoint conference.If active conference is point-to-point meeting, then two terminals can be opened the LSD channel and send data to the other side at this moment, and two terminals can both receive the other side mutually on video channel data (are seen the other side's image mutually, can abbreviate " image is seen mutually " as), so unidirectional and bidirectional data transfers mechanism all realizes, should realize then that the process of unidirectional and bidirectional data transfers mechanism finished.If currently be multipoint conference then advance to step 315;
In step 315, local video conference terminal A sends CCA message, and request Chair token, MCU respond this request, give local video conference terminal chairman A token;
In step 320, local video conference terminal A sends a VCB message, the parameter of this message is M/T number of teleconference television terminal B, MCU responds this message, give all other terminals in the meeting with the broadcast of images of local video conference terminal A, this teleconference television terminal B has just seen the image of local video conference terminal A like this;
In step 325, local video conference terminal A sends a VCS message, the requested image choosing is seen, the parameter of this message is M/T number of teleconference television terminal B, MCU responds this message, the image of teleconference television terminal B is sent to local video conference terminal A, so far, two station terminals under the multipoint conference condition have realized that image sees that mutually bidirectional data transfers mechanism is implemented;
In step 330, local video conference terminal A sends DCA-L message, application LSD token, MCU responds this request, give teleconference television terminal B with the LSD token, like this, local video conference terminal A has just had the power that sends data on the LSD channel to teleconference television terminal B in multipoint conference, and so far the one-way data transmission mechanism also is implemented.
Need to prove that what one-way data transmission among the present invention and bidirectional data transfers referred to all is logic function, and independent entity is not necessarily arranged.Because bidirectional data transfers possesses the function of one-way data transmission simultaneously, thus also can use bidirectional data transfers mechanism to realize the one-way data transmission, and needn't realize the one-way data transmission mechanism separately.
Turn back to Fig. 2 now, in step 215, local video conference terminal sends starting and upgrading message.Local video conference terminal A sends starting and upgrading message by the LSD channel, and B starts software upgrade process with notice teleconference television terminal.This message is actually the H.281 message of an expansion, specifically belongs to action (Action) message wherein, and following table has provided the structure of starting and upgrading message:
Table 1:
| In proper order | Length (byte) | Implication |
| 1 | 1 | Action code is fixed as 0x08 |
| 2 | 1 | The upgrading direction, the software of the software of 1-upgrading opposite end, 2-upgrading local terminal |
| 3 | 1 | Want the type of upgrading software code |
Wherein, first is the action code of 1 byte, and H.281 agreement has been used 0x01-0x07, it is made as 0x08 here, and teleconference television terminal B isolates starting and upgrading message by the action code of 0x08.
Second portion is with byte representation upgrading direction, this direction is to define with respect to the terminal that sends starting and upgrading message, the software of 1 expression upgrading opposite end, the software of 2 expression upgrading local terminals, the upgrading direction has been determined transmitting terminal and the receiving terminal in the software code transmission course simultaneously, the upgrading direction be that 1 o'clock local terminal is that transmitting terminal, opposite end are receiving terminal, be 2 o'clock then just opposite.For present embodiment, that send starting and upgrading message is local video conference terminal A, the direction of then upgrading is 1, and software, the local video conference terminal A of expression upgrading remote video conference terminal B are that software code transmitting terminal, teleconference television terminal B are receiving terminal.
Need to prove, be the starting and upgrading message that is sent to teleconference television terminal B by local video conference terminal A in the present embodiment, i.e. the software upgrade process that is started by local video conference terminal A.In other cases, also can send starting and upgrading message to local video conference terminal and start software upgrade process by the teleconference television terminal, in the case, the value of the upgrading direction part in the starting and upgrading message is 2, promptly the terminal that sends this starting and upgrading message is carried out software upgrading, the terminal that receives this message is the software code transmitting terminal.
Third part is wanted the type of upgrading software code with a byte representation, terminal may be divided into software code several different types and manage (such as according to audio frequency, video, multiplexing division) respectively, may only need wherein one or more of upgrading during practical application, this upgrading software type of code can be specified in this part, the words of the software code of a plurality of types if upgrade, can repeatedly carry out software upgrade process, each different software code of upgrading of specifying.
In step 220, use bidirectional data transfers mechanism to open data channel.In this step, two terminals are opened a data channel of agreement in advance on the basis of the bidirectional data transfers mechanism that has realized, this channel can be a kind of in the normal data channels such as LSD, HSD, MLP or H-MLP of protocol architecture regulation of H.320 video conferencing, can be that two terminals stop to send video data and the video channel that frees out temporarily, can also be the part time slot in the above-mentioned channel.In the present embodiment, local video conference terminal A (teleconference television terminal B) is after sending (reception) starting and upgrading message, stop at and send video data on the video channel, in escalation process subsequently, two terminals are directly used the video channel of free time as the data channel that is used to upgrade.
In step 225, on data channel, set up update channel.Update channel is used for control, response, state information and the software code data of transmit software upgrades process.
After update channel foundation finished, local video conference terminal A and teleconference television terminal B communicated on update channel, finish the transmission of software code.
At first, in step 230, the configuration information that the version of two terminal switch softwares, size etc. are relevant with upgrading.These configuration informations comprise the size of wanting the upgrading software code and version number etc.
In step 235, local video conference terminal sends the software code data of some bytes to the teleconference television terminal by update channel.
In step 240, the teleconference television terminal is by update channel receiving software code data.
In step 245, judge whether end of transmission of software code data, if end of transmission, then this process finishes, otherwise changes step 235.
In the present embodiment, configuration information in the step 230,235 and software code data all are to transmit by update channel in the mode of message bag, and wherein each message bag is made up of several bytes.Message wraps on the video channel as update channel to be transmitted, the content of same message bag is transmission continuously in order, first byte of the message bag in back follows hard on last byte transmission of previous message bag, two terminals all to self up video channel transmission packet and receive the message bag from descending video channel.
Following table has provided the form by the message bag of update channel transmission:
Table 2:
| In proper order | Field name | Length (byte) | Implication |
| 1 | Stem | 4 | As beginning flag, content is always 0x12 0x56 0x34 0x78 |
| 2 | Length | 4 | The total length (byte) that comprises all fields of this message bag of stem |
| 3 | Sequence number | 4 | Initial value is zero, and every transmission a piece of news then sequence number adds 1 |
| 4 | Code | 4 | The type that shows this message |
| 5 | Parameter | Indefinite | Difference with code field changes, and length deducts 18 for the message total length |
Wherein, first is the fixing stem of content of 4 bytes, as the beginning flag of message bag;
Second portion is the length of 4 bytes, provides the total length of this message bag;
Third part is the sequence number of 4 bytes, whether has judged whether information drop-out continuously by the inspection sequence number when teleconference television terminal receives the message bag;
The 4th part is the code of 4 bytes, provides the type of this message bag;
The 5th part is adjustable length message parameter, dissimilar message bags, and the length of its parameter is all different with implication.
Following table has provided the value and the corresponding implication of code in the message bag:
Table 3:
| Message code | Type of message | Parameter length | Meaning of parameters |
| 1 | In the connection | 0 | Do not have |
| 2 | Connect | 0 | Do not have |
| 3 | Fill | Indefinite | Meaningless |
| 4 | Code attribute | 8 | Attribute that will the upgrading software code, preceding 4 bytes are version number, back 4 bytes are the code size |
| 5 | Code data | Greater than 8 | The code data that preceding 4 bytes are this transmission is with respect to the start offset address of first byte of code, and 4 bytes are the quantity of unit with the byte for the code data of this transmission subsequently, and byte subsequently is code data |
Wherein, " in the connection " and " being connected " message are used in that correct the localization message bag---this process can be called synchronously by the byte stream of video channel transmission;
" filling " message is used to keep the synchronous of message sink;
" code attribute " and " code data " message is used for transmission code information.
The usage of these different types of messages will describe in detail hereinafter.
To be local video conference terminal and teleconference television terminal begin action flow chart till upgrading is finished from setting up update channel to Fig. 4.As shown in Figure 4, this process is unwrapped the beginning from send and receive message at video channel.At first, step 405 to 420 is that both sides communicate the process of shaking hands on update channel.
In step 405, the message bag type that transmission is set is " in the connection ".
In step 410, come from byte stream, to isolate one by one message in the mode of searching message header, and obtain the type of message according to previously defined message format.In order to prevent erroneous judgement, must be continuous receive " in the connection " or " connecting " message five times and just can change next step 415 over to, otherwise repeat this step, obviously, this step comes down to the video data that receives is received synchronous process according to the form of message bag.
In step 415, the message bag type that transmission is set is " connecting ".
In step 420, also can receive enough " in the connection " or " connecting " message in order to guarantee the opposite end, synchronous to the reception of message bag to realize, " connecting " message will send five times at least.If sent at least five " connecting " message and also received " connecting " message of the other side, mean that then two terminals have all realized receiving synchronously, think this moment and shake hands successfully, change step 425, otherwise repeat this step.
In step 425, judge whether local terminal is the transmitting terminal of software code, be then to change step 430, otherwise change step 445.
In step 430, send " code attribute " message, the version of software code and size are all taken from the software code of the respective type that transmitting terminal moving, and (version of code is the numeral of one 4 byte in this example, if adopt character string to represent version number, then can revise the form of " code attribute " message).The code data of local terminal to be sent the pointer zero clearing after sending message.
In step 435, send pointer according to code data, the software code data of some bytes are read in the relevant position of the software code of the respective type of using from local terminal, construct " code data " message and send, correspondingly, upgrade code data and send pointer.
In step 440, judge whether the software code data send to finish, be that then this process finishes, otherwise change step 435.
In step 445, being provided with and sending type of message is " filling ".The employed video channel of update channel is a channel that bandwidth is constant, requires the message bag uninterrupted to send, otherwise that the opposite end will lose the reception of message bag is synchronous.Transmitting terminal must not send " filling " message when having other kind of message to send, synchronous with the reception of keeping the opposite end, and the parameter of this message is meaningless, and length is as the criterion to realize the purpose of filling.
In step 450, wait for receiving " code attribute " message that receiving terminal must receive preparation according to the information in this message.If received " code attribute " message, then change step 455, otherwise repeat this step.
In step 455, receive " code data " message, take out software code data wherein, and preserve.
In step 460, judge whether code data receives, if not, then change step 455, if then this process finishes.
Though more than by exemplary embodiment method of the present invention is described in detail, above embodiment is not exhaustive, those skilled in the art can realize variations and modifications within the spirit and scope of the present invention.Therefore, the present invention is not limited to these embodiment, and scope of the present invention only is as the criterion by claims.
